VILLIAM A. TUCKER, OF NEV YORK, N. Y.

CAPSULE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 328,623. dated October 20, 1885. Application filed April l0, 1884. Serial No. 127,295. (No model.)

To all whom it may concern:

Be it known that I, VILLLIM A. TUCKER. of the city of New York, in the county and State of New York, have invented a new Capsule-llIoldOiling Machine, of which the following is a specification, reference being had to the accompanying drawings, forming part of the same, in which- Figure l is a side elevation of a machine embodying my invention. Fig. 2 is a detail drawing of a portion of said machine. Fig. 3 is a plan of said machine. Fig. 4. is a ver tical section of the same on line z z, Fig. 3. Figs. 5 and 6 are vertical sections of the same respectively on lines x fr and y y, Fig. 3, and Figs. 7 to 12, inclusive, are detail views of separate parts of the machine, particularly described hereinafter.

The purpose of my invention is the cleaning and oiling preparatory to the molding capsules thereon of a series of capsule moldpins iixed in a plate as ordinarily arranged for molding capsules to be cut or trimmed in capsule-cutting machines commonly in use. This purpose I accomplish by bringing into contact with the mold-pins a strip or belt of flexible elastic material carrying the oil, looping the same upon the pins, first on one side and then on the other, and, while the oiling-belt is thus looped upon the pins, rubbing the same back and forth on the pins.

I will proceed to describea machine in which the said operations may be conveniently performed and mechanical motive power ernployed therefor.

The frame on which the working parts of the machine are mounted consists of twoside plates, A A', connected at their ends by suitable cross-bars, B B. (See Fig. 1, Sheet 1.) In the said plates are wide openings GG', (see Fig. 5, Sheet L1,) into which to slide ver tically therein are fitted plates D D. same figure.) On the inner faces of these plates, at their upper and lower edges, are formed inwardly-projecting ribs or anges d d d2 d3, which extend across the faces of the said pla tes and some distance beyond the side edges of the same, as seen in Figs. 7 and 12 on Sheet 5.

a a'aaaQsee Fig. 5, Sheet 4) are guide-plates secured to the inner faces of the frame-plates A A', with their inner edges projecting over (See the upper and lower edges of the openings C C', thus furnishing ways or bearings against which the inner faces of the flanges on the plates D D bear and slide.

E (see Fig. l, Sheet 3) is a vertical plate,in which are xed the pins or studs b, (see same figura) which carry the oiling devices, as hereinafter described. On the side edges of this plateare formed guideplates c c', Fig. 5, Sheet 4, extending laterally on either side of said plate E, at right angles to its opposite faces.

A side edge view of E, and an outer face view of one of the plates c, formed thereon, is shown in Fig. l1, Sheet 5, and in Fig. 9 is shown an upper edge view ofthe plate E and the two guide-plates c c. The said plates c c are fitted to slide horizontally between the ribs or flanges d d d2 d, and are held in place by being dovetailed at their upper and lower edges into the said ribs, as seen plainly in Fig. 5, Sheet Ll. By this arrangement the vertical plate E is mounted to reciprocate horizoni tally in theplates D D,and thelattcr are held and allowed to reciprocate vertically in the openings C C' in the side plates, A A', of the frame.

F, Fig. 1, Sheet l., is a eross-bar secured to the rear ends of the wingplates c c, and to this bar is jointed a pitman or connecting rod, G which is pivoted at the opposite end to a swinging lever, H, that is pivoted at e, Figs. 1 and 4, Sheets l and 3, in a bracket, I, secured to the frame. This lever is vibrated by means of a driving-shaft, J, and a crank-pin in the end ofthe said shaft, that works in ajournal-box, J, fitted to slide in an opening, J,

in the lower end of the said vibrating lever. J

The said shaft is also journaled in the bracket I, and is provided with a driving-pulley, L, and a loose pulley, L. (See Sheet 2, Fig. 3.)l By the described means a horizontally-reciprocating motion is given to the wing-plates c c', and of course to the plates E.

K is a shaft journaled in the frame immediately over the upper edge of the plate E, and provided at either end with a crank-pin, ff, that extends from the shaft outside of the frame, and pivoted on these crank -pins at their upper ends and on studs g g are con necting-bars h L, by means whereof a vertical reciprocating motion is given to the plates c ICO f c', and through them to the plate E. The

Y portions of the same.

shaft K is provided with a handle, z', by which it may be rocked by hand on its bearings to give the said reciprocating motion to the platel E, as seen in Figs. 2 and 3, Sheets 1 and 2. In this plate E are fixed a series of studs, b, which studs are slotted longitudinally from their outer ends throughout the projecting ln these slots, in each line or row of the pins, as seen in Fig. 5, Sheet 4, is arranged a belt or ribbon of a suitable flexible and elastic material,(indicated in said figure by the letter l) which maybe a looselywoven cotton fabric of a similar' texture to lamp-wicking. These ribbons or belts are to be supplied with oil in any suitable way for the lubrication of the mold-pins, as hereinafter described.

The plates D Dare held in their normal position midway between the top and bottom of the'openings C C' by springs j j j ja, one above and another below each of said plates, the convex curves of the. springs resting against ledges or rabbets k lc k" k3 (see Figs. 7 and 8, Sheet 5) in the inner faces of the side plates, A A', and the ends against the ribs d d d2 da on the plates D D', the joint action of these springs being to maintain the said plates in the position shown in Fig. 5, centrally between the upper and lower ends of the said openings C C', while they may, by means of the eccentrics on K and the connecting-rods h h', together with the plate E, on which they are formed, be reciprocateyd vertically, as before described.

M'is the moldplate, in which are xed the mold-pins m,in rows corresponding in arrangement and distance apart with the studs b in plate E,4 there being provided one more row each way of the studs b than there are moldpins, as shown in Fig. 4, Sheet 3.

N is a cross-head arranged to slide horizontally in Ways o o', provided in the side plates, A A', ofthe frame. (Shown in Fig. 3, Sheet 2.)

O (see Fig. 4, Sheet 3) is a plateholder secured against the inner face of the said crosshead N by tting the lower edge into a groove formed in a rib, n, at the lower edge of the cross-head, and by a flange, p, at the upper edge, which extends over onto the upper edge of' the cross-head, and is there secured by a screw-bolt passing through the flange into the Y cross-head. By this arrangement the said plate-holder can be conveniently connected with and detached from the cross-head. Near the lower 'edge of the plate-holder O is acleat or stop-bar, q, secured thereto by a bolt, and then, there being provided a number of screwholes in said plate-holder O, the position of the said stop-bar may be shifted vertically to accommodate various sizes of mold-plates, so when a mold-plate rests upon the said stopbar the molds in the plate will be in proper position with relation to the studs in the plate E.

P is a rod or bar secured adj ustably in the front face of the cross-head N, and extending through the end of the frame B, with a spiral spring, r, placed upon it outside of the frame, one end of the spring bearing against the frame, and the opposite end against a collar, fr; A strap or 'chain, r2, is attached at one end tothe outer end of the bar P, and passes over a pulley, s, and its opposite end is attached to the foot-board s', hinged to the base of the frame. By these means the' said crosshead may be reciprooated horizontally in its ways,as the operator by pressing with his foot upon the foot-board will force the cross-head inward toward the center of the frame against the stress of the spring r, and when released from the said pressure the cross-head will be forced back into the rst position 'by the action of the said spring.

z| is a broad spring secured centrally in the frame to a rod, R, fixed in the upper part of the frame, the said spring being so arranged that when the cross-head with the moldplate M is driven inward toward the plate E the said spring t will bear upon the upper edge of the said mold-plate M and hold it in place during the operation of oiling the molds, as hereinafter described.

u is a piece of thick felting or other equivalent material that is spread over and secured to the inner face of the plate E, the studs b passing through holes in the said felt. rlhis is designed to hold the oil with which the molds are to be lubricated, and it may be saturated with the oil in any convenient manner.

The operation of this machine is as fol-y lows: The mold-plate carryingthe molds to be oiled and cleaned being dropped into its place in the cross -head, the latter is then forced toward the plate E by the operators pressing upon the foot-board s until the ends IOO of the molds press against the felt u and take up upon themselves oil from the said felt, the several rows of molds passing in between the several rows of studs b. Then by rocking the shaft K the plate E is forced downward, thus bringing the webs or belts Z into contact with the pins on their upper side, so as to loop the belts around the pins, as seen in Fig. 5. Then reciprocating motion is communicated to the plate E by the means before described, and the molds are oiled and cleaned by the rubbing of the belts Z upon the molds. Then the shaft Kis rocked in the opposite direction, whereby the plate E is raised vertically, and the belts are thus brought in contact with the mold-pins on their lower side while the reciprocating motion of the plate E is continued. The shaft K is then released from the hand of the operator, and the plate E assumes its rst position under the combined action of the springs j j j2 ji. The pressure is then removed from the foot-board s', when the crosshead will` by the stress of the spring 1^ bey drawn back into the position shown in Fig. 4, and the mold-plate is then removed from the cross-head and. another is inserted for a repetition of the operation.

IIO
